From: Use of Direct Gradient Analysis to Uncover Biological Hypotheses in 16S Survey Data and Beyond
Direct gradient analysis of lung explant OTUs at phylotype resolution constrained by subject.
The bacterial communities of human lung explants were binned at a phylotype resolution and constrained ordinations were constructed using the explant from which the sample originated as the constraint. Ordinations were CAP (constrained analysis of principle coordinates) based on (A) Bray-Curtis distance, or (B) Jaccard distance; (C) RDA (the constrained form of PCA); (D) or CCA (the constrained form of CA). Individual samples were colored based on the explant from which they were obtained.
